Re: Questions about binding to heterogeneous collections and to base classes?

Hi Paul,

> 1. Is it possible to bind to a IList<object>

It is preferable to use BindingList<T> instead of List<T>, or rather
IBindingList instead of IList. The binding list supports notifications
and other features required for normal data binding.

I think, no. I may be missed something though.

Yes. It doesn't take a look at the objects. It looks only at the
declared type of the list item.

You may create the IList<MySubClass>, bind it to the input panel to
create controls, then call the C1InputPanel.SetDataBinding() method
passing IList<MyBaseClass> in the first parameter and 'false' in the
last (populate). This doesn't repopulate the panel with controls.
